Medication Therapy Management in the Primary Care Setting: A Pharmacist-Based Pay-for-Performance Project

摘要

Objectives: To evaluate the effect of medication therapy management on chronic disease management and generic drug prescribing in the clinic setting. Methods: Private insurer initiates Pay-for-Performance (PFP) project for clinic-based pharmacists in Iowa and South Dakota (n = 9 clinics) in 2009. Each pharmacist was assigned ~ 300 patients with at least I of 4 disease states (diabetes mellitus, hyperlipidemia, hypertension, and asthma). Pharmacists were expected to complete 2 medication reviews for each patient. The primary outcome was frequency of patients achieving goal levels: diabetes: hemoglobin Alc (Alc) <8%, low-density lipoprotein (LDL) <130 mg/dL, and blood pressure (BP) < 140/80 mm Hg; hypertension: BP < 140/90 mm Hg; hyperlipidemia: LDL <130 mg/dL; and asthma: percentage of persistent asthmatics on controller medication. Generic prescribing rates were evaluated for antihypertensives, cholesterol-lowering agents, proton pump inhibitors, and antidepressants. Results: A total of 827 patients at 3 clinics were included in the analysis. For diabetes, 77.1% had AI c <8%, 83.2% had LDL < 130 mg/dL, and 76.3% had BP < 140/80 mm Hg. For hypertension, 86.2% had BP < 140/90 mm Hg. For hyperlipidemia, 80.6% had LDL < 130 mg/dL For asthma, 100% were on controller medication. One medication review was completed on 88.8% of patients. Generic prescribing rates ranged from 65.8% to 79.4%. Implications/Adaptability: A high percentage of patients achieved goal levels at clinics with clinical pharmacist services. A multidisciplinary approach to patient care may improve disease state management and medication cost savings.
